After visiting the Caixa Forum we hopped on the Metro and went to the Matadero. It’s a converted abattoir that now hosts some interesting exhibitions. We saw the five light installations by Daniel Canogar called Fuegos Fatuos (Fatuous Fire) which were quite pretty in places. There was a really interesting exhibition at the back of the Matadero which explored artificial life, communication and the ability of machines to learn.
